Short description Morphology | Morphometrics

Dorsal soft rays (total): 64-72; Anal soft rays: 49 - 54; Vertebrae: 39 - 41. The species is distinguished by the following characters: vertebrae 11 + 28-30 = 39-41, dorsal fin rays 64-72, anal fin rays 49-54; outer pseudoclasper is broad, wingshaped with single curved supporter; inner pseudoclasper with three lobes, consisting of a branched supporter, anterior branch curved and long, posterior branch short, and a thick fleshy lobe in between; penis with no abrupt change in thickness; opercular spine with single, sharp tip in small specimens and bi- or tri-furcated in specimens > 45 mm SL; scale patch on cheeks is broad, with 8-10 vertical scale rows; otolith length: height ratio 2.2 (Ref. 57883).

Apparently lives on rocky bottoms (Ref. 57883).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00175 - 0.01142), b=3.10 (2.88 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.5 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (12 of 100) .
